For every decimal place that you move over, add one to the exponent of the 10.
So in this problem, you would move nine spaces to the left, so the exponent above the 10 would be a nine.
Therefore, the scientific notation would be:
4.4982529 x 10^9
Cancel y values
multiply 2nd equation by 4 and add to first
-9x+4y=8
<u>-12x-4y=16 +</u>
-21x+0y=24
-21x=24
divide both sides by -21
x=24/-21
x=-8/7

The value of m<BOC if both angles are vertically opposite is 41 degrees
<h3>Vertically opposite angles</h3>
Vertically opposite angles are angles that are equivalent to each other and meet at a point of intersection X
Given the following angles
m∠AOD = (5x − 4)° and
m∠BOC = (4x + 5)°,
If the angles are vertically opposite, hence;
5x - 4 = 4x + 5
Collect the like terms
5x - 4x = 5 + 4
x = 5 + 4
x = 9
Determine the measure of <BOC
m<BOC = 4x + 5
m<BOC = 4(9) + 5
m<BOC = 41 degrees
Hence the value of m<BOC if both angles are vertically opposite is 41 degrees
